Proposed is an RFID antenna module in which feed pins of a patch antenna are connected to a first coupler and a second coupler so that the patch antenna operates as a left hand circular polarization antenna and a right hand circular polarization antenna. The proposed RFID antenna module comprises first to fourth feed pins penetrating through a laminate in which a dielectric, an upper patch, and a lower patch are laminated, and the first to fourth feed pins are spaced apart from each other.
